Setting IP Addresses
Note
All Subnet mask values are the same for all nodes and are set to
255.255.255.0 (except Remote Aux panels with earlier software).
If the default network configuration does not fit your existing Ethernet con-
figuration, they may be changed as explained in the next section to conform
to the in-house standards for your facility. Make sure all nodes have unique
node addresses and are placed on the appropriate network. If other devices
are present on the network, ensure that each device has a unique IP
address. If more than one Zodiak system resides on the same network, the
IP address of each additional Zodiak system device must be changed
before it is connected to the network.
See your network System Administrator before connecting the Zodiak
system to an existing network or making any IP address changes. The IP
addresses (including any Subnet mask) of all the Zodiak devices on the
network must be known before any changes are made.
Fundamental IP Routing Concept
In summary, there are two devices situated on either side of the Video Pro-
cessor frame, the Main panel (sometimes referred to as the Real Time or RT
panel), and the Menu panel. If you change the host IP address of one end
node, then you must update the other end node's IP address table so that it
knows how to reach the node you just changed. For example, if you change
the Menu panel's host IP address from 192.168.54.8 to 192.168.54.10, then
you must change the Main panel's IP address to the Menu panel to
192.168.54.10. You do not change the Main panel's host IP address in this
scenario.
If, however, you change the frame's IP addresses, then you must change
both the gateway addresses and the target IP addresses to the Video Pro-
cessor frame for the Main panel and Menu panel. The reason you perform
this step is the following:
•
Each end node knows how to talk to the Video Processor frame (these
are the target IP addresses to the Video Processor frame), and
•
Both end nodes know how to send packets to each other by using the
Video Processor frame as a gateway or conduit through which the
packets flow (these are Gateway addresses).
